From PicOS 2.6, we added the CPU rate limit for processes of PicOS. Including pica_lcmgr, pica_sif, and ovs-vswitchd.


  • The default CPU usage is 40% if not provided, and default memory size is 150 MB. 
  • The warning message will be printed if the memory size is bigger than the default value.
  • The CPU limitation is based on all CPU's on the system. If the system CPU is P2020 dual cores, 40% CPU limitation is equal to 80% single CPU.


Running CPU/memory rate limit tools manually as follows:

sudo /pica/bin/system/tools/pica_monitor -v -c 40 -m 150 pica_lcmgr

Checking CPU/memory rate limit tools as follows:

admin@XorPlus$ps -aux | grep pica_monitor                      
warning: bad ps syntax, perhaps a bogus '-'?
